Insights

This case report details successful open-heart surgery on an elderly patient with situs inversus totalis and anomalous left coronary artery. Both aortic valve replacement and coronary artery bypass grafting were performed, highlighting surgical feasibility in rare anatomical variations.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Medical Genetics

Background:

  • Situs inversus totalis (SIT) is a rare congenital condition where major visceral organs are mirrored.
  • Anomalous origin of the left coronary artery (ALCA) is another rare congenital anomaly.
  • The simultaneous occurrence of SIT and ALCA presents unique surgical challenges, particularly in elderly patients.

Observation:

  • An 87-year-old female patient presented with symptomatic aortic stenosis.
  • The patient was diagnosed with both situs inversus totalis and anomalous origin of the left coronary artery.
  • This combination of rare conditions in a very elderly patient is unprecedented in existing literature.

Findings:

  • The patient successfully underwent aortic valve replacement (AVR) and coronary artery bypass grafting (CABG).
  • A saphenous vein graft was used for bypass to the left main trunk.
  • The surgical procedure was performed without significant difficulty, with the operator positioned on the patient's left side.

Implications:

  • This case demonstrates the feasibility of complex cardiac surgery in patients with rare congenital anomalies.
  • It suggests that careful pre-operative planning and surgical adaptation can overcome anatomical challenges.
  • The successful outcome in this elderly patient broadens the potential surgical options for individuals with combined SIT and ALCA.

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Thoracic Aorta01:15

Thoracic Aorta

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Coronary Circulation01:21

Coronary Circulation

The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Heart Valves01:16

Heart Valves

The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
